Cloud computing arrived in the technology market to stay. Those who still have questions or think the cloud is just a fad, just look at the numbers to change the mind. Forrester analysts estimate that by 2020, the cloud will be about 15% of the global IT market. A recent survey shows that 66% of companies in india believe that the cloud is vital to business success, and IDC forecasts show that the market turnover of US $ 257 million in 2013 and should reach US $ 798 million in 2015.

The growing demand is motivated by the well known benefits of cloud, such as the optimization of costs, reduction of delivery time (servers and applications), and the system availability improvement. Although these benefits apply to companies of all types and sizes, the cloud brings a special advantage for small and medium enterprises, which often goes unnoticed: access to an almost unlimited amount of computing resources.

If we think on how the market was five years ago, it would be impossible to imagine a small business managing process petabytes of information, or by using thousands of servers to meet the demand of its customers. With the power of cloud computing, however, this is not only possible, but common. Hundreds of companies have appeared on the market with business models that are only possible because of the cloud technology.

Imagine a media company with access to the same content delivery infrastructure, an internet company with access to the same number of servers and disks that Google use, or a small e-commerce with the same ability to process data like Amazon or eNlight Cloud. It is this equality of power that cloud computing brings, especially for Indian entrepreneurs.

Indians have always been one of the most creative people in the world, but this creativity has always been limited by our access to resources of all kinds. Cloud computing levels such access in the field of technology, allowing us to put our creativity into practice like never before been possible. With that, the sky is the limit for the national entrepreneurship.

The process of evolution of the media and various technologies are clearly reflected in the lives of individuals and businesses in general. With the evolution of internet, companies are using various possibilities to leave their increasingly competitive products or services on the market. Among the various known and advantages that businesses can use the Internet, are the concept of cloud computing and grid computing. The following addresses the concept of grid computing and cloud computing, as well as their differences.

What is grid computing?

Nowadays the processing capacity is limited, both in our personal computers or servers in several companies. Now imagine having the arrangement further processing rate so that the server processing is at the peak demand, i.e. without the need to know all the computing apparatus that exists through this processing. This concept of processing is called Grid computing.

Grid computing aims to combine processing power of thousands or even millions of small computers connected in local networks or long distance networks to be able to process large tasks on a given server. The grid computing applications run on a virtual server, which has integration with other resources that are able to share resources quickly and are easily managed.

What is cloud computing?

Cloud computing aims to provide all the computing resources as a service over the internet. An example is that in the early nineteenth century, during the industrial revolution, the industries had to produce their own electricity or mechanical. Nowadays industries consume energy as a service, paying only for what they use. Cloud computing has a similar proposal, where computing resources will be the responsibility of specialized companies, which will manage the resources and market them as a service over the internet.

Cloud computing can be described as a huge environment of virtual or physical servers, reaching a concept of computing resources that include processing power, storage, connectivity, platforms, applications and services available on the Internet.

Conceptual differences between Grid and Cloud Computing

There is always a confusion between the concept of cloud computing and grid computing, as both share the same cost reduction objectives, increase flexibility and accessibility features.

The concept of grid computing basically offer processing power through some mechanism, since cloud computing is to provide every cell of computational resources on demand, over the internet and consuming as a service. Despite the similarities, the paradigms work with different concepts that can work together or work in isolation.

A cloud computing model is the SaaS (Software as a Service). In this model, software solutions are offered over the internet, that is, the company does not need license purchases to have a solution, but only needs to hire a service from a provider that offers office applications. An example is an office application solution that is free, like Google Docs.

The two concepts discussed in this article have similar goals, but work in different ways and for different purposes.
